[RFC] Event timers on Marvell SoCs

Hi.
I've made a patch, updating Marvell SoC timers driver to utilize new MI
event timer infrastructure. There are two main benefits:
- unified interfaces and behavior with other platforms,
- support for timer in one-shot mode.
Code was successfully tested on Sheevaplug (Marvell 88F6281).
Patch for HEAD can be found here:

Any comments?
